Meanwhile, after the power of the product is cut off, the time of the inertial vibration of the vibrator is long, so that the satisfaction degree of user experience is reduced to a great extent. Therefore, there is a need for a new vibration device to overcome the above-mentioned drawbacks.
The present invention provides a vibration device, including: the vibration assembly comprises a balancing weight, a first magnet group and an elastic piece, the first magnet group is fixed on the balancing weight, and the vibration assembly is suspended in the vibration device through the elastic piece; the stator assembly comprises a coil and a second magnet group, and the second magnet group is arranged in a winding hole of the coil; the first magnet group comprises at least two side magnets, and the magnetizing directions of the two side magnets are perpendicular to the plane where the coil is located; the two side magnets are reversely magnetized; the magnetizing direction of the second magnet group is parallel to the plane where the coil is located, and two poles of the second magnet group are respectively attracted with the magnetic poles of the two side magnets close to the coil; the vibration assembly is configured to vibrate relative to the stator assembly.
The vibration device according to the present invention may be a vibration motor, an exciter, etc., and the content of the present invention is not limited thereto.
As an embodiment of the present invention, as shown in fig. 1 or 2, the vibration device includes a vibration assembly. Alternatively, the vibration assembly is used as a vibrator of the vibration device, suspended inside the vibration device. The vibration assembly includes a weight 10 for providing a greater mass when the vibration assembly vibrates to increase the vibration inertia of the vibrator and thus the vibration amplitude. Optionally, the balancing weight of the present invention may be a tungsten steel block. The tungsten steel block has higher density, and the tungsten steel block has higher mass in the metal blocks with the same volume. Therefore, the counterweight block made of the tungsten steel block has smaller volume, which is beneficial to reducing the volume of the vibration device. The vibration component further comprises a first magnet group 20, and the first magnet group is fixedly arranged on the balancing weight. When the first magnet group generates vibration, the vibration amplitude of the first magnet group can be increased by using the mass of the balancing weight. Optionally, the vibration assembly further comprises an elastic member 30 fixedly connected to the weight block. The elastic piece is used for providing vibration damping for the vibrator and preventing the vibrator from colliding with other parts of the vibration device due to overlarge vibration amplitude. Meanwhile, the elastic piece provides vibration restoring force for the vibrator and promotes the reciprocating vibration of the vibrator. Optionally, the vibration assembly is suspended inside the vibration device by an elastic member. The vibration device also includes a stator assembly. The stator assembly includes a coil 40 and a second magnet set 60. The second magnet group is arranged in a winding hole of the coil, and the winding hole of the coil refers to a hole left in the middle position of the coil after the coil is wound. The first magnet group comprises at least two edge magnets. Alternatively, referring to fig. 3, the two side magnets are identical in size and opposite in magnetizing direction. The magnetizing direction mentioned here is a direction from the S pole to the N pole in the magnet. The magnetizing directions of the two side magnets are vertical to the plane of the coil. The two side magnets are parallel to each other and are symmetrically arranged relative to the center of the coil. And the second magnet assembly 60 comprises a magnet that is magnetized in a direction parallel to the plane of the coil. And the two poles of the second magnet group are respectively attracted with the magnetic poles of the two side magnets close to the coil. Specifically, the second magnet group is arranged in parallel to the plane where the coil is located, and the magnetizing direction of the second magnet group is along the arrangement direction of the second magnet group. Two magnetic poles of two limit magnets close to the voice coil loudspeaker voice coil are S utmost point and N utmost point respectively, and the N utmost point of second magnet group and limit magnet are close to voice coil loudspeaker voice coil S utmost point and attract each other, and the S utmost point of second magnet group and limit magnet are close to voice coil loudspeaker voice coil N utmost point and attract each other. In the structure, the second magnet group generates attraction force which is symmetrical to the two side magnets when the vibration device is in a static state. The attractive force can increase the number of magnetic induction lines of the side magnets 201 and 202 passing through the coil 40, thereby improving the utilization rate of the magnetic flux of the coil. Meanwhile, the existence of the attraction can ensure that the vibration component generates symmetrical vibration relative to the central position of the vibration device, and can also prevent the excessive vibration of the vibration component. In addition, after the coil stops supplying power, the attraction can shorten the inertia vibration time of the vibration component, and magnetic damping effect on the vibration component is generated.
In the invention, the vibration component can generate vibration relative to the stator component. As an example, the vibration assembly is suspended above the stator assembly, when alternating current is applied to the coil 40, the coil is acted by an ampere force, and the movement of the coil generates a force which counteracts the first magnet assembly 20, so that the vibration assembly vibrates in a certain direction in a horizontal plane. The second magnet set 60 generates a symmetric attraction to the two edge magnets of the first magnet set to mitigate polarization of the vibrating assembly that deviates from the direction of vibration. The vibration device further includes a flexible circuit board (FPCB)90 for passing an electric signal into the coil. Optionally, the FPCB is attached to a side of the coil facing away from the first magnet group. Optionally, a pin is reserved on the FPCB for connecting an external circuit. Optionally, the vibrating device further comprises a washer 80. The washer is used for conducting magnetism for the first magnet group.
The second magnet group 60 is used for attracting the first magnet group 20 to generate symmetrical attraction force to the two side magnets of the first magnet group, so that a good centering effect on the vibration component can be formed, and the vibration performance of the vibration device is improved. Meanwhile, the existence of the attractive force generates a magnetic damping effect on the vibration assembly, so that the time from power failure to vibration stop of the vibration assembly can be shortened, and the user experience is effectively improved.
Optionally, the vibration device includes a first housing and a second housing, and the second housing is fastened to the first housing to form an inner cavity of the vibration device; the vibration assembly is suspended in the inner cavity; the stator assembly is fixed on the first shell in the inner cavity.

In particular, the vibrating assembly is suspended within the internal cavity described above. The elastic member 30 may be attached to the first housing or the second housing to suspend the vibration assembly within the cavity. Optionally, the stator assembly is fixed to the first housing within the inner cavity. Specifically, the coil is fixed to the first housing through a flexible circuit board 90, and the second magnet group 60 is mounted in a winding hole of the coil. The first shell and the second shell can be used for protecting the components of the vibration device and preventing the external factors from interfering the movement of the vibration device.
Optionally, a connecting portion is disposed at an edge of the first housing corresponding to the elastic member, and the elastic member is connected to the connecting portion; the connecting part is arranged in a concave mode relative to the edge of the first shell.

Specifically, the edge of the first housing is provided with a connecting portion 501, and the elastic member is fixedly connected to the connecting portion 501, so that one end of the elastic member can be fixed, and the elastic recovery function of the elastic member can be further exerted.

Alternatively, referring to fig. 4, the connecting portion 501 of the present invention is recessed with respect to the edge of the first housing, that is, the connecting portion is recessed toward the center of the first housing, and is spaced from the edge of the first housing by a certain distance. This structure facilitates the snap-fit mounting of the second housing 70 on the first housing, maximizing the storage space for the components in the vibration device. Alternatively, the escape distance of the connection may be the wall thickness of the second housing. This is advantageous in that the outer dimension of the second housing is fully utilized to form the maximum accommodating space. Or the avoiding distance of the connecting part is larger than the wall thickness of the second shell, so that the vibration component and the second shell can be prevented from vibrating and interfering.
Optionally, an edge local area of the first shell protrudes outwards and is bent to form the connecting part.
